Where he had paused to snarl back defiance at his enemies there was a big red spatter on the ground; from this point to the summit they followed a crimson thread of blood.
Three times in descending into the other valley they found where Thor had stopped, and each time they saw where a pool of blood had soaked into the earth or run over the rock.
They passed through the timber and came to the creek, and here, in a strip of firm black sand, Thor's footprints brought them to a pause.

Bruce stared.

An exclamation of amazement came from Langdon, and without a word having passed between them he drew out his pocket-tape and knelt beside one of the tracks.
"Fifteen and a quarter inches!" he gasped.
"Measure another," said Bruce.
"Fifteen and--a half!" Bruce looked up the gorge.
"The biggest I ever see was fourteen an' a half," he said, and there was a touch of awe in his voice.

"He was shot up the Athabasca an' he's stood as the biggest grizzly ever killed in British Columbia.

Jimmy, _this one beats 'im_!" They went on, and measured the tracks again at the edge of the first pool where Thor had bathed his wounds.
